This is a guide on how to replace a ATMega328P microcontroller (Code: X000048) on an Arduino UNO R3 Board (Model: EL-CB-001, Code: A000066). This guide does not require any specialized skills or knowledge.

The ATMega328P processes the instructions in C from the Arduino IDE. If damaged, the code cannot be executed. Fortunately, replacing the microcontroller is a simple and uncomplicated process. Before starting the repair, please unplug the the Arduino board from the USB.

    • On the right side of board, position a nylon spudger in between the microcontroller and the dip socket, and gently lift upwards to pry it out.

    • The bottom of the microcontroller can be scratched if not done carefully. Do not use a metal tool for this step.

    • Repeat the same process on the other side.

    • Lift both sides evenly to prevent any damage to the pins.

    • If needed, straighten the pins of the replacement microcontroller and place it directly over the dip socket.

    • Make sure the notch on the side of the microcontroller is facing the right, matching the white lines on the board.
